Are you a SysAdmin? Are you also a gamer? Do you use the Steam platform? If you answered yes to all three of those questions, you have a new group that you can join. It’s the ServerFault Steam group.

While the group’s name and logo show strong ties to ServerFault, one does not have to be a member of ServerFault to join the group (although it might help for familiarity’s sake). The group is new, with no home on the web beyond the steam group page nor is there an event calendar. However, we’re still young and the opportunities are limitless.

Join up, help out and we can help… umm… decommission some users. Load your LARTs and ready your PODs. It’s game time!

Seriously, Cisco Press. What is your problem? I used to think you were incompetent. Now I think you’re deliberately evil. They explicitly stated that transport layer traffic that uses UDP is called a “datagram.” That stands to reason. After all, UDP is a TLA for “User Datagram Protocol.” Then, immediately afterwards, they state (emphasis mine):

However, this book refers to data formed in the transport layer as a segment, data at the network layer as a datagram or packet, and data at the link layer as a frame.

No rhyme. No reason. Just fiat. “Hey, we know that it’s standard practice to call a specific type of Layer 4 traffic a datagram, but we’re gonna call Layer 3 traffic a datagram. Or we might also call it a packet too, JUST ‘CAUSE WE’RE GANGSTAH LIKE THAT!“

For those wondering, I’m brushing up on my networking knowledge by going through “Interconnecting Cisco Network Devices, Part 1 (ICND1): CCNA Exam 640-802 and ICND1 Exam 640-822 (2nd Edition)” It’s already caused me to make the first part in this series. A series which will likely have many sequels.

I’m not even halfway through it and already finding some annoying inconsistencies. I thought I left things like this behind when I stopped reading MS Press books. Apparently vendor endorsed books have a disproportionate amount of fail in them.

I’ve been researching web-based server control panels for a few months now. Most people will likely think of cPanel when they hear the phrase “server control panel” and have visions of web hosts dancing in their heads. Server control panels can be used for much more than web hosting, however. Control panels can allow people to administer systems with the click of a button having little interaction with the gorier details. Some might think that kind of scenario is categorically wrong, but I disagree. There are some *NIX oriented colleagues that I’d tackle before they got too close to a Windows server. For them, WebsitePanel might be a better option. There are also some folks that have need of their own server(s) and are happy to perform their own button mashing to reboot services and etc. I’m reminded of Jordan Sissel’s SysAdvent post “Share Skills and Permissions with Code.” In those scenarios, server control panels are excellent.

The nature of server control panels makes them most desirable by web hosting companies. As such, most of the web-based server control panels that I have found are slanted in that direction and might take some creativity to warp to your needs. Others appear to be more easily used as a general “E-Z Mode” SysAdmin front-end (Open Panel comes to mind). Don’t discard a control panel simply because it is slanted to web hosting. Some of them are much fuller than that.

Here is my list of web-based server control panels:

FOSS Control Panels

• DTC (Linux, FreeBSD and Mac OS X Server. GPL license. Stands for “Domain Technologie Control.” Looks like a great feature set. I don’t know why it’s not more popular.)
• EHCP (Linux only. GPL license. Stands for “Easy Hosting Control Panel”)
• Froxlor (Linux and BSD. GPL License. A fork of SysCP. )
• GNU Panel (Linux only. BSD license. Just kidding! It’s GPL.)
• ISPConfig (Linux only. BSD license. Made by the HowToForge folks. HTTP, SMTP, FTP, DNS and OpenVZ virtualization are supported among many other features)
• IspCP Omega (Linux only. Fork of VHCS. Old VHCS code is MPL, new code is GPL2. The goal is to port everything and make it GPL2.)
• Open Panel (Linux only. GPL license. Their pre-made OpenApps looks cool. I don’t know why this hasn’t made more waves than it has!)
• SysCP (Linux only. GPL license.)
• VHCS (Linux only. MPL license. Stands for “Virtual Hosting Control System”)
• WebController (Windows. only GPL. SourceForge project with an appalling website. Looks like it’s abandoned but I’m not sure.)
• Web-CP (Linux only. Not sure what license, but I assume GPL since it was a fork of the older web://cp product that itself was GPL. Web-CP looks abandoned. The last update on the site was 2005 and the latest bug closed in Mantis is 2006. The wiki is full of spam [I've never seen spam for breast enlargement and pistachios on the same page before - Thanks Web-CP!])
• zpanel (Windows and POSIX-based OSs – that includes Max OS X.)

Control Panels with a Free and Paid Edition

• Webmin (Primarily POSIX-based OSs, however a limited Windows version exists)
• Usermin Module (POSIX only. Simple webmail interface and user account modification for non-root users)
• Virtualmin Module (POSIX only. Allows for multi-tenant use of a server much like a shared web host)
• Cloudmin Module (POSIX only. Creats VPSs using Xen, KVM and OpenVZ among others)

Commercial Control Panels

• cPanel / WHM (Linux and FreeBSD. The granddaddy of control panels started back in 1996 as an in-house app that eventually got licensed. WHM controls the entire server. cPanel is user-oriented.)
• WHMXtra (Not a control panel on its own, but it’s a significant third-party add-on to WHM)
• DirectAdmin (Linux and BSD.)
• Ensim (Control panel that handles the management of cloud services Microsoft Hyper-V, Active Directory, Lync, Mozy, Anti Virus / Anti Spam Solutions like F-Secure, MessageLabs, Barracuda and a ton of other things. It’s really for $n aaS providers to build a business around.)
• Enkompass (Windows only. cPanel’s Windows product.)
• H-Sphere (Windows, Linux and BSD. Originally made by Positive Software before being bought by Parallels. I’m not sure how this software compares / competes with Parallels’s Plesk. This is an all-in-one provisioning, billing and control panel tool. Obviously focused solely on web hosts.)
• HMS Panel (Linux only.)
• Hosting Controller (Windows and Linux. Also supports managing Microsoft Exchange, BlackBerry Enterprise Server, SharePoint, Office Communication Server, Microsoft Dynamics and more.)
• HyperVM (Linux only. Virtualization management platform. Uses Xen and OpenVZ. Sister product to Kloxo.)
• InterWorx (Linux only. Can manage Ruby on Rails.)
• Kloxo (Linux only. More than just a server management platform, this is a large web hosting platform that is geared very much for a client / provider relationship.
• Machsol (Unusual in this list because it’s a control panel to manage the hosting of major enterprise server applications like Exchange, Sharepoint and BES.)
• Parallels Helm (Windows. One of the many acquisitions that Parallels has made.)
• Parallels Plesk (Linux and Windows. Probably the biggest competitor to cPanel.)
• SolusVM (Linux only. Manages VPSs and VPS clusters using OpenVZ, Xen and KVM.)
• vePortal (Linux only. CentOS only. Uses OpenVZ. One of the lowest price control panels.)
• WebsitePanel (Windows only. The former dotnetpanel after it was revised by SMB SAAS Systems Inc. and released as a SourceForge project.)
• xpanel (Rather emaciated looking control panel with very low price. Only advertised to run on Fedora.)

Billing / Automation Tools for Control Panels

These are billing and automation tools that tightly integrate with control panels.

Misc. Inclusions

I’d like for this to become a definitive list of web-based control panels (regardless of their focus; server management or web hosting). Basically, if it can manage a server or services and has a web front-end, I’d like to know about it. I’d appreciate any social shares. Likes, +1s, Tweets, Stumbles, Digg’s and etc. are awesome. If you know of any control panels that I’ve missed (active or defunct, since I love history), or if you spot a control panel that I mis-categorized, please let me know in the comments below.

Oh Cisco Press. Why must you annoy me so.
